I find that using no 1 pins in new blocks is not a problem unless fit too
tight but what pin isn't. I don't have any trouble with no. ones otherwise.
I'll read the article, really! I can't deny that no 2 are stiffer
but ones render nicely when fit well which is why I like them.</font></font></blockquote>

Dale,
<p>Part of the problem, even when you read the article, is that it's in
two installments, and the February issue isn't out yet. The answer
to your question will probably lead to more questions, all of which are
addressed fully in the article. The simplest answer, however, is
that in a Steinway the string height above the pin block - not the plate
- is roughly three times greater than it is in an open face design like
a Bechstein. Since the string tension is roughly the same, the leverage
exerted by the string on the pin is three times as great. If the
pin sizes are the same in both cases, pin flex will produce roughly three
times as much string movement in the Steinway as in the Bechstein - i.e.
it is less stable. Going to a larger, stiffer pin size will partly
compensate for that.
<p>Chances are that at this point we get into "but what about...," in which
case I get to rewrite the whole article on line. I would just as
soon wait for the February Journal. There will probably still be
plenty to debate, but at least not the stuff I've already covered in the
article.
<p>Best regards,
